how do you know that the CKC has a true bloodline? On the CKC website it tells you that all you need to regerter a dog with then is three pictures and some signatures of people to say that the dog is that breed. with an AKC you know what you are getting.

As pointed out above. WHICH CKC. The contKC calls itself CKC to ride on the Canadian Kennel Club's coat tails.. which is a reputable, if not on a few points better registry than the AKC, it's sometimes more hardcore on it's breeders.

I have just purchased a male Yorkie, he is to be AKC registered, they gave me DNA for his father and both papers from AKC for parents. I am really worried he might not be pure, he is 12 weeks and already weighs 7 pounds. Can anybody comment?

Dont have pictures of him yet, and yes I have papers for registration for him. I did take him to the vet and she said he was indeed 12 weeks; and that his weight just meant he will be very healthy, rather than those that are tiny.

How big were the parents? Did you see them--even in a picture? When you are looking at a dog for breeding you should ALWAYS look at the parents--grand parents too if any are on site.

BTW-- my friend purchased a 'yorkie' which turned out to be a silkie terrier. Not much difference in looks--big difference in size. Also you may want to test the 'DNA' info of the parents against a sample from the puppy. It is 'possible' that the breeder is wrong about the parentage of the puppy--on accident or intentionally.
